Also there is a sound coming from my rear left tire I jsut put new drums and pads on teh back and its still making the noise
Your back wheel might be a baad wheel bearing causing the noise. Have it checked out. As far as mileage, check for dirty air filter, fuel filter, etc. There are many reasons for it. Have engine scanned for codes and check fuel pressure. Check your fuses in car as well a underhood as you may have one blown.
